This looks more like the ryu didnt know that match up. You did alot of fake pressure that he allowed you to get away with.
blocked fireball/store is -2, and following up of st.mk is 6(+2 = 8) frame startup, b.hk is 7(+2= 9) frame startup.
Its such a risky stituation he can counter hit you with ryu’s b.hk which is 8 frame startup and beat both options
On hit its a different story provided you are close enough fireball on hit is +4 so you can get st.mk and b.hk in there that way.
This is assuming you are right up against him to get the first hit of st.mk.
However I did like the fireballs done with spacing is more advantageous to yourself, however the ryu player could just fireball you back, or dp which he did the one round and won.
